Enhanced single-particle brightness and photostability of semiconductor polymer dots by enzymatic oxygen scavenging system

Single-particle fluorescence brightness of polymer dots exhibits a two-fold increase by an enzymatic oxygen scavenging system. The photostability of Pdots in the oxygen scavenging system was significantly improved as compared to those in water, providing a useful approach for enhancing single-particle brightness and photostability in long term imaging and tracking applications.252
